Description

Detailed Description of the Invention

Technical Field

[0001] The present invention relates to a transportation, storage, and carrying system for workers at a construction site to carry and store necessary items such as tools and building materials into the work site and carry them for work.

Background Art

[0002] Tool holders for holding tools and the like on a worker's waist belt or the like are known. For example, there is a holder body attached to a belt-like wearing body and a tool bracket that can be inserted into the accommodation space of the holder body. The tool bracket accommodated in the accommodation space is engaged and held with respect to the holder body in a state where it is prevented from coming out by a stopper portion. Also, when removing the tool bracket from the holder body, a tool holder has been proposed that can be easily removed by sliding the stopper portion obliquely downward and pulling up the tool bracket upward (see, for example, Patent Document 1).

[0003] Also, a toolbox has been proposed that consists of a toolbox main body 1, a connection holding body 2, and a drawer body 3. A fitting connection recess 17 with the connection holding body is provided on the bottom surface of the toolbox main body, and the connection holding body is provided with a connection support column 23. By attaching the connection holding body to the main body, a mounting space for the drawer body is formed and drawer storage is attached (see, for example, Patent Document 2).

[0004] Furthermore, in order to prevent the load of the loaded goods from collapsing during transportation, a trolley has been proposed in which a net or a string is hung on the loaded goods for fixing (see, for example, Patent Document 3).

Summary of the Invention

Problems to be Solved by the Invention

[0005] It has a tool bracket that can detachably hold a tool with respect to the holder body. As tools in the tool holder, for example, in addition to a hammer, a bar, a ratchet wrench, an electric driver, a measuring tape, etc., it is described that it includes a bag for storing tools, a tool holder, etc. These various tools, tool bags, tool holders, etc. can each be individually attached to the tool holder. If the shapes of the tool brackets are made common and a plurality of tool holders are pre-mounted on the operator's waist belt, etc., it is possible to carry all the tools according to the work content. Also, even when the work content changes and the tools used accordingly change, it is possible to select only the appropriate tools, recombine them, and carry them, optimizing the tools around the waist and improving work efficiency.

[0006] On the other hand, tools that have become unnecessary according to the work content can be removed together with the tool brackets from the tool holders mounted around the operator's waist, or exchanged with other tools that have become necessary again. However, no specific method has been proposed for the storage and preservation of the tools removed from the tool holders. In fact, the operator has been simply and messily storing the tools with the tool brackets still attached in a toolbox, a large bag, etc. Therefore, the present invention proposes a tool storage device that can hold and store the tools removed from the tool holders.

[0007] In addition, when there are multiple toolboxes for storing tools, or when loading building materials and the like required for work onto the work site at the same time, these items are loaded onto a trolley and carried in. At this time, the loaded items on the trolley may collapse. In order to prevent the collapse of the loaded items during transportation, trolleys have been proposed in which a net or string is hung on the loaded items for fixation. However, toolboxes and building materials often do not have matching sizes, and it is not easy to stack them stably on the trolley according to their shapes. Also, the work of hanging ropes front-to-back and left-to-right is complicated. Toolboxes often become heavy, and when overcoming the inertia during trolley movement or ground level differences, the situation becomes even more unstable, and the net or string cannot withstand the weight and comes off the loaded items, often resulting in the collapse of the load. Therefore, the present invention realizes stable transportation of tools to a construction site without performing the work of hanging a net or string by having a structure that is securely connected simply by placing a toolbox on a trolley.

[0008] Furthermore, even when multiple toolboxes are loaded when loading a toolbox onto a vehicle that enters a construction site, due to the influence of inertia and vibration during vehicle operation, the phenomenon of load collapse or movement occurs inside the vehicle. Therefore, the present invention can prevent load collapse and movement inside the vehicle by having a structure that is securely connected simply by placing a toolbox inside the vehicle.

[0009] By using a tool holder having a tool bracket that can detachably hold tools with respect to the holder body, various tools, tool bags, tool holders, etc. can each be individually attached to the tool holder. By standardizing the shape of the tool brackets and pre-attaching a plurality of tool holders to a worker's waist belt or the like, it is possible to carry all the tools corresponding to the work content. Also, even when the work content changes and the tools used accordingly change, it is possible to leave only the appropriate tools, remove or reorganize unnecessary tools, and carry them, optimizing the tools around the waist and improving work efficiency. Also, since there is no need to carry unnecessary tools around the waist, the burden on the waist can be reduced.

[0010] Also, by using a toolbox provided with a storage holder, tools can be easily stored by removing the tools from the waist and directly locking them to the storage holder. Also, instead of storing them haphazardly inside the toolbox, if they are locked to the storage holder and stored neatly, the replacement work of the tools can be carried out quickly even when replacing the tools. Also, damage to the tools during storage can be prevented.

[0011] Furthermore, the toolbox stored by locking the tool holder to the storage holder can be connected to a trolley. By simply placing the toolbox on the trolley, with a structure that ensures connection, the load collapse of the loaded toolbox can be prevented without performing operations such as using a net or tying a string, improving safety. It is possible to achieve safe and stable transportation of tools to a construction site.

Effect of the Invention

[0012] According to the present invention, regarding a transportation, storage, and carrying system for workers at a construction site to carry in, carry, and work with items necessary for work such as tools and building materials, by using a container body provided with a storage holder, workers can easily store tools by removing the tools from around the waist and directly locking them to the storage holder. Furthermore, the toolbox stored by locking the tool holder to the storage holder can be connected to a trolley. By simply placing the toolbox on the trolley, with a structure that ensures connection, the load collapse of the loaded toolbox can be prevented without performing operations such as using a net or tying a string, improving safety. It is possible to achieve safe and stable transportation of tools to a construction site.

Mode for Carrying Out the Invention

[0014] Hereinafter, with reference to the drawings, a tool loading system according to an exemplary embodiment of the present invention will be described.

[0015] FIG. 1 shows the basic configuration of the loading system according to the present invention. It shows a state in which a plurality of container bodies are loaded on a cart. Note that the container bodies are shown by way of example as a drawer box, a tool box, a tool basket, and a tool bag, respectively. In the drawer box, the tool box, the tool basket, and the tool bag, a storage holder for holding tools and a connecting part for connecting and fixing the upper and lower parts during loading are commonly provided.

[0016] FIG. 2 is a perspective view showing the tool basket alone. The tool basket is a box body with an upper opening and an internal storage part formed. It is characterized in that a storage holder having a shape capable of accommodating an insertion part engaged with the operator's waist tool holder is provided along the inner wall part and the outer wall part of the box body. In addition, at the center of the lower part of both side surfaces in the short side direction of the box body, a connecting part that is connected to the lower container body when the container bodies are stacked vertically is provided. In addition, at the center of the upper part of both side surfaces, a locking hole that is connected to the upper container body when the container bodies are stacked vertically is provided. Note that in this embodiment, the tool basket is described as an example, but the storage holders and connecting bodies of the drawer box and the tool box are common and have the same dimensions and component configurations. A storage holder capable of supporting a tool bracket is provided on the peripheral wall of this box body.

[0017] Also, a tool bag is shown in Fig. 3. Since the locking holes are not provided above both side surfaces where only the tool bag is connected to the upper container body, it is planned to be loaded only at the top when connecting, and thus it has a shape that is designed to be stacked only at the top. Incidentally, it is common that both the internal and external storage holders and the connectors connected to the lower container body when the container bodies are stacked vertically are provided at the centers below both side surfaces in the short side direction.

[0018] Fig. 4 shows a drawer box. The drawer box is basically composed of a box body for storing two drawers, one above the other, but it is possible to add and connect one more drawer at the bottom, and it can be used as a drawer with the number of drawers desired by the operator. The drawers include those without partitions as freely usable spaces and those that can lock a dedicated parts case. The dedicated parts case is provided with an insertion part that can engage with the storage holder and a hook that can engage with the drawer. The hook is shaped such that an engaging protrusion is provided on the case side at the tip of a plate-like member extending downward from the upper part of the back surface of the parts case, and when it is hooked on a plate-like part provided inside the drawer and completely stored inside the drawer, the engaging protrusion engages with a slit provided below the upper part of the plate and is fixed. At the upper part of the parts case, an insertion part for the storage holder is provided at a portion corresponding to the base of the hook, and this insertion part also serves as a button for releasing the engaging protrusion engaged with the drawer. That is, since the parts case is made of resin, when the insertion part is pushed as a button, the plate-like hook part bends, and the engaging protrusion separates from the slit of the drawer, so the parts case can be taken out of the drawer by simply pulling it upward.

[0019] The detailed structure of the storage holder will be described. Fig. 5 is an explanatory diagram of the usage state of the storage holder. In the present embodiment, the tool bracket has an insertion part and a spacer part. The insertion part 3 is substantially flat, and inclined surfaces are provided on both sides in the width direction so as to be tapered on the tip side in the insertion direction. Also, a curved notch-shaped positioning recess is formed near the center of the front end surface.

[0020] The storage holder has a bracket holding portion including an accommodation space S on its front side, and is fixed to the wall portion of the container body through a hole provided at the center of the main body using a screw or the like. The bracket holding portion has a frame portion that partitions and forms the accommodation space S, a support protrusion, and a stopper portion. In this embodiment, the accommodation space S is partitioned and formed by a rail-shaped frame portion surrounding the front-rear, left-right directions and a support protrusion erected at the center of the lower side. The frame portion and the support protrusion restrict the movement of the insertion portion 3 disposed in the accommodation space S in the front-rear direction, left-right direction, and downward direction within a predetermined range.

[0021] Also, above the accommodation space S, a tongue piece having elasticity and swingable in the front-back direction of the holder is provided. In this embodiment, the tongue piece extends rightward with substantially the center above the front of the holder body as a base point. Also, a protrusion erected toward the front side is provided at the tip of the tongue piece. When the storage holder is made of resin, the tongue piece can be integrally formed. Also, when the holder body is to have a robust structure and is made of metal or the like, it is also possible to provide an elastic resin-made tongue piece by assembling it from the back side of the holder body. The tongue piece restricts the upward movement of the insertion portion disposed in the accommodation space S. That is, the tongue piece is biased in the front direction of the holder body by the elastic force of the material thereof, and when the insertion portion is inserted into the storage holder, the insertion portion intrudes into the holder while pushing aside the tongue piece. When the insertion portion is completely mounted in the holder, the tongue piece returns to its original position by its elasticity. The insertion portion 3 accommodated in the accommodation space S is prevented from coming out by the protrusion provided at the tip of the tongue piece. Thereby, the tool bracket is engaged and held with respect to the storage holder in a state where it is prevented from coming out. Also, when removing the tool bracket from the storage holder, when the tongue piece is pushed and swung from the front to the back direction, the tongue piece moves from above the insertion portion to pull up the tool bracket upward, and it can be easily removed. The basic structures and dimensions of the holder and the storage holder are common, and the insertion portion of the present invention is applicable to both the holder and the storage holder.

[0022] Note that the shape and structure of the tongue piece 6b are not particularly limited as long as it can suppress the removal of the tool bracket 1.

[0023] Note that the holder body 2 of the present embodiment is configured to insert the insertion portion 3 from above the accommodation space S, but the insertion direction is not particularly limited. Further, the shape of the insertion portion is not particularly limited as long as it can be inserted into the holder.

[0024] Next, a case where tools are taken out from the toolbox and used for work will be described. FIG. 6 is an explanatory diagram of a situation where an operator uses the tools for work. The work holder is detachably attached around the operator's waist or the like to a belt-like wearing body A such as a belt. The work holder has the same basic structure as the above-described storage holder. A plurality of work holders can be attached, and the operator can attach an appropriate number of holders as needed. By selecting only the tools necessary for the work at that time and attaching them to the holder body, there is no need to carry unnecessary tools, and the tools around the waist can be optimized, improving work efficiency.

[0025] FIG. 7 shows an exploded view of a connecting portion that controls the connection between the container bodies. The main body of the connecting portion has a thin central portion of a rectangular parallelepiped and thick ends. The locking body is plate-shaped, and engaging protrusions are erected at the lower end in the direction of the inside of the container body. The engaging protrusion has a wedge-shaped cross section. Bearing holes are provided on both the left and right sides of the locking portion, and it is pivotally supported by the shaft of the main body and configured to be swingable. The upper part of the locking body is biased outward by an elastic body inside the main body. Further, an intermediate body exists between the main body and the locking portion. The intermediate body is composed of a rectangular parallelepiped that is combined with a concave portion in the center of the back side of the locking body, and is assembled so as to be movable in parallel along a rail portion provided on the locking body. It is biased downward along the rail by an elastic body provided in the concave portion of the locking portion. Further, the upper part of the intermediate body is configured in a wedge shape and is configured to move when the locking portion swings.

[0026] When connecting the container bodies of the present invention vertically, when the upper container body is placed on top of the lower container body, the engaging protrusion of the connecting body provided below the container body contacts the upper edge of the connecting hole provided above the lower container body. Further, when the upper container body descends toward the lower container body due to the self-weight of the container body, since the locking body is pivotally supported by the main body and can swing, it swings against the biasing force of the elastic body and the engaging protrusion climbs over the upper edge of the connecting hole. When the engaging protrusion completely climbs over the upper edge of the connecting hole, the elastic body that biases the upper part of the locking body outward causes the locking body to return to its original position and engage with the connecting hole of the lower container body, so that the upper and lower container bodies are securely connected. Since the connection operation is performed by the self-weight of the container body, the operator can carry tools while preventing the load from collapsing without hanging a net or string and fixing it to a cart.

[0027] When releasing the connection of the vertically connected container bodies, when pushing the upper part of the locking body toward the inside of the container body, the locking part swings against the biasing force of the elastic body provided on the main body, the upper part of the locking body penetrates into the container body, and at the lower end of the locking body, the engaging protrusion is disengaged from the engaging hole of the lower container body. Then, the intermediate body biased by the elastic body downward moves into the space generated below the locking body from which the engaging protrusion has disengaged and prevents the locking body from returning to its original position. As a result, the operator can safely and conveniently release the connection parts connecting both ends of the container body one by one. When the container body is connected to the lower container body again, the intermediate body returns to its original position from its wedge shape.

[0028] The locking body is also provided with a window portion. Through this window portion, the intermediate body that has moved downward of the locking body when the engaging protrusion is released can be visually confirmed from the outside. The presence of the intermediate body visible through the window portion can confirm that the engaging protrusion has been released, which is safe. In addition, if the intermediate body is colored in a color that easily attracts attention, such as red or fluorescent color, it becomes possible to recognize at a glance that the connection has been released, which is even safer. In addition, various means such as the blinking of a light or a buzzer sound can be adopted as a method of indicating that the connection has been released. Also, if a protrusion protruding outward from the window portion is erected on the intermediate body, it is possible to adopt a specification that allows the connection state to be restored by operating this protrusion even after the connection is released.

[0029] Figure 8 is a trolley for loading and transporting the container body. The trolley is provided with a connection hole that can be connected to the engaging protrusion of the container body described above, and it is possible to securely connect and fix the container body. In addition, since the connecting portion for loading and fixing the container body on the trolley of the present invention is provided with an engaging protrusion at the lower part of the container body to be loaded on the trolley, the upper surface of the trolley body is flat, and members related to the connection of the container body do not protrude from the upper surface of the trolley. Therefore, even general box-shaped articles such as cardboard boxes other than the container body according to the present invention can be stably loaded.

[0030] Also, the handle erected at the rear of the trolley body can be rotated around the base on the trolley side and folded down, and can be stored in a groove for storing the handle provided on the upper surface of the trolley body. Also, the wheels of the trolley can be folded and stored inside the bottom surface of the trolley body. Since both the handle and the wheels can be stored, the plate shape of the trolley body can be deformed into a compact shape, and it is convenient to be stored in the gap of the load when stored in a car, etc.

[0031] A guard member is provided at the upper part of the handle of the trolley for the purpose of protecting the hands of the transporter. When loading goods high, in case the goods sway due to vibration or inertia during movement, the guard member is provided so that an operator who transports the goods by pushing the handle of the trolley will not have their hand caught between the handle of the handle and the swaying goods. The guard member is a plate-like member provided on the goods side of the handle so as to cover both hands when the handle of the handle is grasped with both hands. Also, if the width of the guard member is set at a position where it contacts the loaded goods, it is possible to have an effect of making the loaded goods less likely to wobble in addition to the effect of protecting the hands of the transporter.

[0032] In addition, a hanger for hanging and storing a harness safety belt can be hung on the trolley. The hanger is provided with shoulder-hanging parts for hanging the left and right shoulders of the harness safety belt on both the left and right sides near the hook part of the hanger provided in the center, and further provided with leg-belt hanging parts for hanging the leg belt part of the harness safety belt on the outside thereof. Both the shoulder-hanging part and the leg-belt hanging part are provided with protrusions on the outside thereof so that the belt does not slip off in the outward direction of the hanger. Also, the hook part of the hanger is pivotally supported with respect to the main body and has a shape in which two arcs of different sizes intersect. This is a shape set assuming both an arc of a size assumed to be hooked on the handle of the trolley of the present invention and an arc of a size assumed to be hooked on a single-pipe or the like used at a construction site. Further, a storage holder capable of accommodating a tool bracket is provided at the center of the hanger main body, so that items that are desired to be transported without being put in a container body can be hooked on the storage holder of the hanger and carried.

[0033] The container body can be easily transferred from the trolley to an automobile or a motorcycle. It is possible to connect it to a pedestal set on a shelf in a factory or a work shed from an automobile or a motorcycle and store it neatly. Also, if it is stored by connecting it vertically, it is possible to prevent the goods from collapsing due to vibration or the like.

[0034] FIG. 9 is a perspective view showing a second embodiment different from the above description. The second embodiment is a carry box in which a carrier having wheels and a box body which is a container body are integrally formed. Also in the box body of the carry box, the above-described storage holder and connecting portion are adopted. The wheels are provided outside the box body so as not to sacrifice the storage capacity of the box body. Further, since the wheels are not provided by cutting into the box body, the wheels are configured to cover the upper part with a mudguard portion.

[0035] What has been described above is merely an exemplary embodiment of the present invention, and various modifications are possible without departing from the gist thereof.
